ABSTRACT:
A method for interference suppression for TDMA and/or FDMA transmission, which at least approximately can be described as pulse amplitude modulation, with an arbitrary number of receive antennas. The method comprises filtering of at least one complex-valued received signal ri[k] of one receive antenna with a filter with complex-valued coefficients fi[k] for generation of at least one output signal yi[k], forming at least one projection of at least one output signal yi[k] onto a vector piwhich is assigned to this output signal yl[k], summing of a majority, especially all of the output signals yi[k] for forming a sum signal s[k], and feeding the sum signal s[k] into a device for detection, especially equalization. A system for interference suppression for TDMA and/or FDMA transmission is also disclosed.
